List 3 ways muscle action may be determined.

Biology
1 answer:
In-s [12.5K]3 years ago
6 0

Answer:

The muscle action can be determined by:

* Prime Movers and antagonist: Prime movers are also called the agonist, it is the muscle that provides the force that drives the action. Regarding to the antagonist muscle, it is the opposite to a prime mover as it provides resistance or reverse in a given movement. They are paired up on opposite sides of a joint.

* Synergists: There are one (or more) synergists involved in an action, the are muscles that help the prime mover when it is playing its role.

* Stabilizers: Their fuction is to keep bones immobile when it is needed. For example, the muscle of your back, they are stabilizers when the keep your posture sturdy.

Skin stem cell at the g2 checkpoint of the cell cycle contains 14 chromosomes but twice the amount of dna as one in the g1 stage
kotegsom [21]
The diploid number for the specie is 14 chromosomes. Diploid means the paired chromosomes as opposed to haploid which is 7 chromosomes.
G2 or gap 2 phase of the interphase is where DNA synthesis occurs and where the chromosomes are replicated to generate sister chromatids.

Attached earlobes are a recessive trait in humans. In the tree below, people
kramer

Answer:

It would be C

Explanation:

If you look at the tree you can see that one of the male's parents had the recessive allele, and one of the siblings has the ressive allele, the means the male could have the trait but isnt showing it.

In grapes, the wild-type DND1 gene confers resistance to attain viruses, and strains are susceptible to viruses. The EDS1 gene c
Genrish500 [490]

Answer:

I = 62.5%

Explanation:

<u>Available data</u>:

  • the wild-type DND1 gene confers resistance to attain viruses. Strains are susceptible to viruses
  • The EDS1 gene confers resistance to powdery mildew, a type of fungal infection
  • The genes are linked, eight map units apart on chromosome
  • A third gene, IR 1. imparts resistance to certain lepidopteran leafminers and is 10 map units from EDS1 and 18 map units from DNDI
  • The observed double crossover rate is 0.3%

According to this information, we can picture the position of each gene in the chromosome

---DND1----------------------EDS1-----------------------------------IR1---

       ║---------- 8MU---------║------------------10MU-------------║

       ║------------------------------18MU------------------------------║

The map unit is the distance between the pair of genes for which one of every 100 meiotic products results in a recombinant product.

1% of recombinations = 1 map unit = 1cM. The maximum recombination frequency is always 50%.

So, if we know the distances between genes, we know their recombination percentages.

  • DND1-EDS1 = 8 MU = 8% recombination
  • EDSI-IR1 = 10 MU = 10% recombination

To calculate interference, first, we need to know the coefficient of coincidence, CC.    

CC= observed double recombinant frequency/expected double recombinant frequency

<em>Note: </em>

  • observed double recombinant frequency=total number of observed double recombinant individuals/total number of individuals
  • expected double recombinant frequency: recombination frequency in region I x recombination frequency in region II.

CC= (0.003)/(0.08 x 0.1)

CC=0.003/0.008

CC=0.375

CC = 37.5%

The coefficient of interference, I, is complementary with CC.

I = 1 - CC

I = 1 - 0.375

I = 0.625

I = 62.5%

Margaret is a marathon runner, and she knows that with her daily training schedule she needs to eat more protein than an average
Doss [256]

Answer:

63, grams

103, grams

Explanation:

According to the Academy of Nutrition and Dietetics endurance athletes, like Margaret needs about 0.55 to 0.9 grams of protein per pound while Strength-athletes that are trying to build muscle mass need more than 0.9 grams of protein per pound.

Since Margret is an Endurance athletic according to the question she will be needing:

115 lb x 0,55 =63,25 grams

115 lb x 0,9 =103,5 grams

Therefore Margaret should consume between 63 and 103 grams of protein daily.

Describe what occurs to the triceps muscle when the biceps muscle is contracted. Even though these muscles are antagonists, why
aksik [14]

Answer:

The triceps muscle extends when the biceps muscle is contracted.

Explanation:

The biceps and triceps muscles,work together in creating functional movement. These movements contribute to the ability to perform day to day tasks.

These muscles function in flexing and extending the arm. <em>Biceps for flexion</em> and<em> triceps for extension</em>. Both muscles work in an antagonistic fashion such that, the one doing the major motion is called the <em>primary mover</em> while the other muscle, is the <em>antagonist</em>. These muscles work in opposite direction, aiding the movement of the arm in both directions.

When biceps are contracted, the triceps are extended. Their antagonistic nature is beneficial because both muscles set the motion patterns at particular points. If we only had biceps extension of the elbow will be impossible and any movement that requires extension would not have been possible and vice versa.
